Title: Flattened seat structure for automobile
Inventor: ARAI TOMIJI
IPC: B60N2/36
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To hardly deform links and a slide rail by forming escape sections notched from upper sections at least on part of the range where a cushion link and/or a back link can be overlapped on the slide rail on the side view when moved. SOLUTION: When a slide rail 2 is notched from the upper end by the prescribed depth, the escape sections 4, 5 of the inner slide rail 2 covered with an elastic member 3 are formed. The escape sections 4, 5 are provided at the portion where a cushion link 6 and a back link 7 are overlapped on the slide rail 2 on the side view when moved. Even when the cushion link 6 and the back link 7 are rotated and a tool or the like enters between the links 6, 7 and the slide rail 2 in a process that a seat cushion 10 and a seat back 11 are flattened, the tool or the like escapes into the escape sections 4, 5, thus the links 4, 5 do not strongly interfere with the slide rail 2, and both are rarely deformed.

Abstract: PURPOSE:To enable a wide-angle beam scan with the small extent of a decrease in gain, by using two curved surfaces out of a cylindrical, a spherical, and a conic surface in combination. CONSTITUTION:A spherical-surface array antenna 5 and a cylindrical-surface array antenna 6 are used in combination, and electric power supplied to input terminals 11, 12, 13- is shift in phase by phase shifters 21, 22, 23- to be radiated into the air through element antennas 31, 32, 33-. The phase-shift extents of the phase shifters 21, 22, 23- are varied to perform a beam scan within + or -thetas angle range. When the thetas is small, the antenna 5 is used for the beam scan and when the thetas is large, i.e. about 90 deg., the antenna 6 is used; when the thetas is between the both, the antennas 5 and 6 are both used in common for the beam scan. Thus, the beam scan has the small extent of a decrease in gain when the thetas is 0-90 deg. or above it.

Filed: 1981-01-23
Abstract: PURPOSE: To ensure an assured character process with the space between lines set at 0, by inputting the special marks at the head of each line to be printed.  
     CONSTITUTION: A cursor CM is first shifted to a left margin mark LMM on the 1st line, and then a character L (indicating a print without gap) is supplied. Thus the character L is displayed in the mark LMM on the cursor CM. As a result, the character patterns are connected without gap to be printed for the 1st line through the final line. In case the 4th and its subsequent lines are set back to the standard line pitch, the cursor CM is moved to the mark LMM on the 4th  line to supply a character S. Thus the character S is displayed in the mark  LMM on the 4th line. As a result, the 4th and its subsequent lines are set at the  standard pitch.

Title: Amorphous silicon thin film element
Inventor: KANAI HIROMI
IPC: H01L29/40
Filed: 1980-01-30
Abstract: PURPOSE:To make an element available extensively for application by minimizing a step difference between an electrode plane and a substrate plane in the element coated with a noncrystal silicon thin film on the substrate plane provided with the electrode beforehand. CONSTITUTION:A concavity identical in shape with a given electrode 3 is formed on the surface of a substrate 2 through photoetching, and the concavity is metalized for the electrode. Then, metal other than that of the concavity is removed through etching to have a step difference between the electrode plane and the substrate plane at 2,000Angstrom  or below. A metallic electrode shaped as arranged and thick satisfactorily can be formed according to the above constitution, therefore a noncrystal silicon thin film 1 can be formed on the electrode by an arbitrary means like vacuum evaporation, sputtering or CVD. An influence by the step difference around the electrode is therefore eliminated, and thus the noncrystal silicon thin film element suitable for various applications other than a solar battery is obtainable.

Title: Magnetic recording and reproducing device
Inventor: OKUDA TOORU
IPC: G11B20/10
Filed: 1984-01-20
Abstract: PURPOSE:To reduce the cost by providing a multiplexer to simplify the circuit of a reproducing system. CONSTITUTION:Signals such as music signals or the like are subjected to PCM and are recorded. Signals on individual tracks of a magnetic tape are received from the magnetic tape by plural reproducing elements of a reproducing head, and individual channels of reproducing element outputs are switched at a high speed by a multiplexer 6 to join signals. Thereafter, the signal passes a regenerative amplifier and is subjected to parallel-serial conversion similarly to a conventional device and is demodulated and is subjected to CRC check and is subjected to inverse matrix conversion and has error corrected and is subjected to D/A conversion and is outputted. Since the multiplexer 6 is provided to join signals sent to the regenerative amplifier, it is unnecessary to provide plural regenerative amplifiers as conventional, and one regenerative amplifier is enough. Consequently, the circuit of the reproducing system is simplified very much.
